DOOR-SECURER.

SPECIFICATION forming part of Letters Patent No. 359,815, dated March2'2, 1887.

Application filed January 4, 1887. Serial No. 223343. (Model) .Z0 all-whom it may concern:

Be it known that I, CALVIN J. SARGENJ, of Methuen, in the county ofEssex and State of Massachusetts, have invented certain new and usefulImprovements in Door-Fasteners, of which the following is aspecification.

My invention relates to devices of a detachable and portable characterfor fastening or seeming doors in closed position.

It is the object of my invention to provide a device of the naturementioned which may readily be applied to any door to secure the same inclosed position without marring or defacing any part of the door orcasing, and which may be conveniently carried about in the pocket of theuser.

Among the objections attending devices of this nature are that they arenot applicable to door-casings having a peculiar form of molding, oranything but a fiat surface, even with the surface of the door at thepoint where the fastening is app1ied,and in attaching them the door orcasing is more or less marred or damaged. By my improvement theseobjections are entirely overcome,said improvements consisting in a boltadapted to engage the mortise or socket for the latch-bolt, or the boltof the lock,or a mortise orsocket especially provided for the purpose,said first-mentioned bolt extending out from between the door and casingand engaged with a crossbar having an adjustable post connected witheach end, one of which posts is adapted to bear on the door and theother on the casing, all as I will now proceed to describe and claim.

Reference is to be had to the accompanying drawings, and to the lettersof reference marked thereon, forming a part of this specification, thesame letters indicating the same parts wherever they occur.

Of the drawings, Figure 1 represents a perspective view of my device asapplied to a door-casing,a portion of thelatter being shown in section.Fig. 2 is a top plan view of the same. Fig. 3 is a similar view of amodified construction. Fig. 4is a fragmentary view of another modifiedform of the device.

In carrying out my invention I provide a preferably flat bolt, (1,having a portion, b, at

one end bent at an angle to the main or body portion, which angularportion 1) is adapted to engage the socket or mortise 0, formed in thecasing d,-for the latch-bolt or bolt of the lock; or itmay be a mortiseor socket especially provided for the purpose. Toward the opposite endof belt a, I form in the sides or edges thereof, at opposite points,notches c c, for a purpose to be presently explained.

f indicates a cross-bar provided at substantially its center with anelongated slot, 9, adapted to admit thcrethrongh the end of a bolt-,a,when presented in a certain position with respect thereto.

hit represent screwthrcadcd posts, having a screwthreaded connectioneach with one end of the cross-bar f,so that they maybe adj usted' inany position in said crossbar within the limits of their length. Each ofsaid bolts is preferably headed on each end, and, if desired, the endsdesigned to bear against door and easing may be slightly cushioned withrubber, fibrous material, or any other sub -stance,while the oppositeends may be so constructed as to facilitate their manipulation to effecttheir proper adjustment in the crossbar. In the present instance theends .2 e of the posts, designed to bear against the door or casing, areconstructed as washers or rings, upon which the posts proper turn,sothat when the posts are turned in against the door or casing they turnon said washers, which remain stationary, and. thus marring of the dooris avoided.

In operation, the bolt a will be arranged with its angular part b in thesocket c of the casing, in which position the door will beclosed,leaving bolt a extending out from between the easing and the edgeof the door. The cross-bar f, with the posts h h attached, will then beapplied to bolt a by turning it to such position as to admit the outerend of said bolt through slot 9, in which position said cross-bar isslipped on the bolt to such of the notches c as it may be most desirableto have it secured, when the cross-bar will. be turned substantially aquarter-way around, the elongated form of the slot permitting of lateraladjustment of the posts to the desired point, in which position theinner end of one of .the posts will be brought to rest on the door andthe other on the casing, the posts being adjusted to accommodate them toany unevenness or variation in the plane of the surfaces of the door andeasing or molding on the latter, on which the inner ends of said postsmay bear. If the door and. adjacent casing are light and thin, so thatthe bolta will project outwardfarenough for the cross-bar to be engagedwith theinnernotehes, 0, it will be secured at that point; but if adifferent condition of things exists, so that the bolt a projectsoutward but a short distance from the door, the cross-bar may be securedin the other notches of said bolt. This provision, and the fact that theposts h h can be adjusted in the cross-bar to compensate for anyunevenness of the surfaces on which they are made to rest, adapts thedevice to doors and. casings of varying form or character,and whensecured inpla'ce will effectively hold the door in closed position.

Another point to be noted is thatin my device noneot' the parts isprovided with spurs or similar features, which are driven into the dooror casing, as is common in most contrivances of this character, andhence marring or damaging any of the parts is entirely avoided.

In Fig. 3 I have shown a modified manner of connecting the cross-barfwith the bolt. In this instance the outer end of said bolt is providedwith a screw-thread, and has a thumb nut, z, fitted-thereto. Ahoie isformedin the cross-bar of a character adapted to admit thescrew-threaded part of the bolt thereth rough, after which the thumb-nuti is applied and turned into the desired position.

It is obvious that with .this construction one i form, therein at aproper point after the crossbar has been moved to proper position onathebolt a.

These different constructions are shown to indicate the changes that maybe made inithe form and. arrangemeutof the parts comprising my inventionwithout departing from its nature or spirit.

Having thus described my invention,what I 1 claim is--- A door-fastenerconsisting of bolta,provided with the angular part b, cross-bar f,detach-- ably connected with the outer end of said bolt,

and screw-threaded osts hh' havin a screwthreaded connection with theends of said cross-bar, as set forth.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing Witnesses, this 27th day of December, A. I).1886.
